Mosquitoes alone transmit diseases to more than 700 million people annually. Culex quinquefasiatus mosquitoes are transmitters of diseases like malaria, filaria dengue fever, chinkunguniya and Japanese encephalitis which are among the most serious vector borne diseases. Malaria is a major global health problem. Malaria alone kills 3 million each year, including 1 child every 30 seconds. Botanical pesticides are preferred in comparison to synthetic pesticides, as they are eco-friendly and bio degradable. Plant derived extracts possessing insecticidal activities are no doubt safer and receiving increasing importance as an alternative to synthetic pesticides.
